One possible version:
Dear Editor,
Yesterday afternoon our monitor led the whole classmates to have a discussion about the good and bad
sides of setting off fire-crackers during the Spring Festival.We had different viewpoints on it.Some of us
believed that setting off firecrackers during the Spring Festival is a Chinese cultural tradition and it certainly
adds pleasure and joy to the festival.What's more,it may help the people to get rid of evil things.But others
of us held that setting off firecrackers during the Spring Festival may cause air and noise pollution.What's
worse,it sometimes causes terrible accidents to children and our property.
Could you tell me what your opinions are,then?
Yours truly,
Li Ming
